* '''Single Protocol'''. The BSX app supports a single protocol that uses an incremental load test with 3 minute stages. If you want to do any other test protocol, such as longer stages or something closer to the MLSS protocol, you can't.
* '''Single User'''. The BSX is sold as a single user device, and the software does not readily support sharing the device.
* '''Usefulness'''. I have two concerns around the usefulness of BSX. The first issue is that [[Tempo Runs]] don't appear to be an effective form of training, so the value of knowing your Lactate Threshold seems rather limited. However, the BSX could still be of value if it's a viable measure of training intensity, especially for [[High Intensity Interval Training]]. Typically, [[Heart Rate TrainingDrift| Heart Rate Training suffers from drift]], so something more reliable might be useful. However, in my testing I found that the BSX did not seem to meaningfully reflect my training intensity. During either the BSX incremental treadmill tests or during [[High Intensity Interval Training]] the BSX showed a relatively stable muscle oxygenation. This is in contrast with the [[Moxy]] system that showed a better relationship between intensity and muscle oxygenation. The only noticeable change in muscle oxygenation that I saw with BSX was during the initial transition from walking to running.

I have a number of concerns with the validity of the results of the BSX.
